Abstract:
:The use of an indirect fluorescent antibody test (IFAT) performed in a "sandwich" technique has demonstrated: (i) the usefulness of the test for the diagnosis of Trypanosoma cruzi infection in the opossum Didelphis marsupialis; (ii) the existence of differences in the serological response of the opossum, that were related to the parasite strain and were clearly evident during the follow-up of experimental infections in laboratory born specimens; (iii) that, despite a good correlation between serological and parasitological examinations, IFAT was the most sensitive diagnostic test used, followed by xenodiagnosis; and, (iv) that in general, the opossum D. marsupialis seems to be a good responder to T. cruzi antigens.
